Unwrapping errors.Join error to []error through type assertion.

[forgoty]

I am trying to type assert multiples errors created with errors.Join

err := errors.Join(errors.New("err1"), errors.New("err2"))
errs, ok := err.(interface{ Unwrap() []error })

This code results in a warning:

type assertion on error will fail on wrapped errors. Use errors.As to check for specific errors (errorlint)
        errs, ok := err.(interface{ Unwrap() []error })
                    ^

This is a valid case for me from go 1.20. Seems should be whitelisted.

Fixed! Thanks for reporting :)
